alkenes with MgCl2 as the chlorine source. This method provides operationally simple, sustainable, and efficient access to a variety of vicinally dichlorinated compounds. In particular, alkenes with oxidatively labile functional groups, such as alcohols, aldehydes, sulfides, and amines, were transformed into the desired vicinal dichlorides with high chemoselectivity. Mechanistic data are consistent with

A continuous flow-friendly organocatalyticchlorination of alkenes has been developed. The method implicates the catalytic system PhS(O)Me/TMSCl and makes use of environmentally benign H2O2, as the stoichiometric regenerator of the sulfoxide catalyst. Under these conditions, internal disubstituted and terminal alkenes cleanly convert to the corresponding anti-dichlorides, while electron rich trisubstituted
已经开发了连续流动友好的烯烃有机催化氯化。该方法涉及催化系统 PhS(O)Me/TMSCl,并利用环境友好的 H 2 O 2作为亚砜催化剂的化学计量再生器。在这些条件下,内部二取代和末端烯烃干净地转化为相应的反二氯化物,而富电子的三取代或 1,1-二取代烯烃提供烯丙基氯化产物。

The phenylselenenyl chloride adduct from alkenes can be oxidised and the selenomoiety can be displaced by chloride to give high yields of dichlorides with cis geometry.
